as the last, but of more erect habit, growing about 2 feet high. Not 

 very hardy. 



C. Corbariensis {Salvifolius x populifolius). —Forms a compact 

 bush about 2 feet high. Leaves glutinous ; margins fringed. 

 White flowers about i^ inches across, with a yellowish centre, in 

 June and July. 



C. crispus. —Gxovfs about 2 feet high, with large flowers of 2 to 3 

 inches across, of rosy crimson, flowering from June to November.

C. cyprius. — Grows up to 5 feet high. Dark green leaves, smooth 

 above and hoary beneath, which in winter assume a glaucous tint. 

 Flowers borne in clusters, white, with a dark base and petals, and 

 4 inches across. Flowers in July. A very good shrub, often sent 

 out as the Gum Cistus. 



C. fiorentinus {monspeliensis x salvifolius). — Grows from 12 to 

 18 inches high. Compact habit. Dark green leaves and large white 

 flowers, with base of petals yellow, borne in the summer in the 

 greatest profusion. Quite one of the best of the dwarf kinds. 



C. formosus (syn. Helianthemum formosus). — Rather a loose 

 habit. Grows up to 3 feet high. Small hoary leaves and yellow 

 flowers, with a dark purplish-brown blotch at the base of each 

 petal. Very pretty, but liable to succumb in a hard winter. As it 

 strikes easily from cuttings, a stock should be kept to replace 

 casualties. 



C. glaucus. — Grows about 2 feet high. Dull green glabrous 

 leaves, downy underneath. Large white flowers with a yellow 

 blotch. Pretty. 



C. hirsutus. — Leaves downy on both sides. Flowers white, with 

 yellow base. Rather smaller than the last, which it otherwise 

 resembles. Grows up to 2 feet high. 



C. ladaniferus (Gum Cistus). — Grows about 3 feet high. Dark 

 glossy leaves, white and woolly underneath. Large white flowers, 

 4 to 5 inches across. Blooms in June to August. A well-known 

 and handsome shrub, not very hardy everywhere.

 base of petal. Otherwise the same as above, of which it is a 

 variety. 



C. laurifolius. — Flowers white, with a yellowish mark at the base 

 of each petal, but otherwise similar to the above, except that it is 

 very hardy, standing any amount of cold and wet. Grows readily 

 from seed or cuttings. Blooms in June. 



C. lusitanicus. — Grows about 18 inches high, of rather prostrate 

 habit. Dark green, slightly viscous leaves, and large white flowers, 

 each petal having a yellow base, with a dark green maroon blotch 

 above it. A lovely little shrub, and quite one of the best.
